The advertised rate on a fixed-term deposit isn't what you keep — taxes and the exact term change the real return. This calculator computes your net annual yield from principal, rate, and term, so you can compare deposits on an apples-to-apples, after-tax basis.

When to use this calculator

Compare the real, after-tax return of a 30-day vs a 60-day fixed deposit.
Check whether a deposit's net yield beats monthly inflation before rolling it over.
Decide between a traditional fixed deposit and a money-market fund on a net-yield basis.
Project how many pesos a $5,000,000 deposit nets over a year for cash-flow planning.
Estimate the net effective annual rate (APY) of a deposit rolled over all year.

Argentine Fixed Deposit: Net APY by Nominal Rate and Term (15% withholding, 2026)

Nominal Annual Rate	30-day term — Net APY	60-day term — Net APY	90-day term — Net APY
60%	65.6%	68.4%	71.3%
70%	78.5%	82.3%	86.2%
80%	91.7%	96.6%	101.7%
90%	105.3%	111.4%	117.7%
100%	119.2%	126.7%	134.5%
110%	133.5%	142.5%	151.8%
120%	148.1%	158.8%	169.5%

Net APY = ((1 + TNA/100 × days/365)^(365/days) − 1) × 0.85. Tax: Argentine income-tax withholding 15% on interest (AFIP, 2026).

How it works

How It Is Calculated

A traditional fixed-term deposit in Argentina pays simple interest on the principal over the agreed term. The base formulas are:

Gross interest = Principal × (Nominal annual rate / 100) × (Days / 365)
Total at maturity = Principal + Gross interest

In Argentina, individuals (personas humanas) pay a 15% income-tax withholding (Impuesto a las Ganancias) on the interest from peso fixed deposits (art. 97 of Law 20.628, introduced by the 2017 reform and in force since 2018). The bank acts as withholding agent and credits the net amount directly:

Withholding = Gross interest × 0.15
Net interest = Gross interest × 0.85

> Important: the withholding applies to resident individuals. Companies (personas jurídicas) settle income tax differently and are not subject to this withholding at source.

To compare returns across different terms, you calculate the effective annual rate (TEA, Tasa Efectiva Anual) — the Argentine equivalent of APY. It measures how much the principal would earn if you rolled the deposit over at the same pace for 365 days:

Gross APY = (1 + (Rate/100) × (Days/365))^(365/Days) − 1

The APY is always higher than the nominal rate for short terms because it captures the effect of compounding on each rollover. A 30-day deposit rolled over 12 times is not the same as multiplying the monthly rate by 12; each rollover capitalizes the previous period's interest.

Concrete Example

$1,000,000 at 97% nominal for 30 days:

Item	Amount
Gross interest	$79,726
15% withholding	$11,959
Net interest credited	$67,767
Total at maturity	$1,067,767

Rolled over all year at the same rate: gross APY ≈ 154% — net APY ≈ 122%. The gap between the two reflects exactly the cumulative effect of the withholding on every monthly rollover, not just one.

---

Useful Context

Legal minimum term: the BCRA (Argentina's central bank) sets a minimum term of 30 days for peso fixed deposits (Communication A 7718 and updates). There is no single minimum for every product type; UVA deposits, for example, have different minimums.

UVA fixed deposit: adjusts the principal for inflation (CER index) plus a small real rate. This calculator applies only to traditional fixed-rate peso deposits, not to UVA or dollar deposits.

Reference rate: the BCRA publishes minimum rates for retail fixed deposits (individual deposits up to a certain amount). The rates banks offer can run above that floor. Always confirm the effective rate your bank agrees to, not the generic system rate.

Day-count basis: Argentina uses the ACT/365 convention (actual days over 365). Do not use 360 days: you will underestimate the real interest credited.

Common Mistakes

Confusing the nominal rate with the APY. The bank advertises the nominal annual rate (TNA). The APY (TEA) — which reflects the real return if you roll over — is always higher for short terms. At 30 days, the difference can be 30 to 50 percentage points depending on the rate level.

Forgetting the 15% withholding. The bank deducts it automatically at maturity. What lands in your account is already net. Comparing the gross interest with what you received causes confusion about "why I got less."

Assuming the withholding applies to everyone. Companies, non-resident investors and certain special regimes are treated differently. This calculator models the standard case of a resident individual.

Ignoring the opportunity cost of the tax. In a high-inflation environment, the capital withheld for income tax that is not reinvested loses purchasing power. The real net APY (after inflation) is what actually matters for preserving capital.

Comparing different terms by total interest. $50,000 of interest over 60 days is not better than $30,000 over 30 days unless you calculate the APY. The correct comparison is always on an annualized basis.

Final Note

This calculator is an approximate reference. Rates change frequently in Argentina; always verify the current rate with your institution before deciding. For significant amounts or particular tax situations, consult a licensed accountant.

$1,000,000 for 30 days at 97% nominal

Gross interest = $1,000,000 × (97/100) × (30/365) = $79,726

Income tax 15% = $79,726 × 0.15 = $11,959

Net interest = $79,726 − $11,959 = $67,767

Net total at maturity = $1,000,000 + $67,767 = $1,067,767

Net APY (rolled over all year) ≈ 122.1%

Net interest: $67,767 — you collect $1,067,767 at maturity (net APY ≈ 122.1%).

Frequently asked questions

What is a fixed deposit?

A fixed deposit is an investment where you commit funds for a fixed period at a guaranteed interest rate. You earn returns based on the principal, rate, and term.

How are fixed deposit returns taxed in Argentina?

Individuals pay a 15% income tax on the interest from peso fixed deposits. The bank acts as withholding agent and deducts it automatically at maturity, so the amount credited to your account is already net. This calculator applies that 15% withholding so you see the real take-home return.

How does this calculator work?

Enter your principal amount, the bank's nominal annual rate, and the term in days. The calculator applies simple interest — Principal × (Rate/100) × (Days/365) — then withholds 15% income tax to show gross interest, net interest, the total at maturity, and the effective annual rate (APY).

What's the difference between the nominal rate and the APY?

The nominal annual rate is what the bank advertises and is applied with simple interest over the term. The APY (TEA) is the effective annual rate you'd earn by rolling the deposit over at the same rate all year, compounding each period: (1 + (Rate/100)×(Days/365))^(365/Days) − 1. For short terms the APY is noticeably higher than the nominal rate.

Can I withdraw early from a fixed deposit?

A traditional fixed deposit is locked until maturity and generally cannot be cancelled early; UVA (inflation-linked) deposits can be pre-cancelled after 30 days at a reduced rate. Plan the term to match when you'll need the money.

Why is the day count 365 and not 360?

Argentine fixed deposits use a 365-day (calendar-year) basis. Using a 360-day basis (the Anglo banking convention) would overstate the return by roughly 1.3-1.4%.

Is the result exact?

The interest math is exact for the inputs you enter. The net figure assumes the standard 15% income-tax withholding for individuals; your final tax position can differ if you have other second-category income, so consult an accountant for large amounts.
